1 Claim.

The present invention relates to devices known as perpetual calendars, the primary object of the invention being to provide a perpetual calendar embodying a casing having a sight opening, and endless webs movable before the openings, in such a way that the indicia on the webs will be displayed indicating the days of the months and months of the year.

An important object of the invention is to provide a device of this character including an endless web on which indicia indicating days of the week are provided, and another endless web operating adjacent thereto, and on which names indicating months of the year are provided, mechanism being provided for the operation of the webs, so that both webs may be operated by knobs located at a point intermediate the ends of the casing at the top thereof where they are readily accessible. 7

Still another object is to provide a calendar embodying independent endless webs, and independent means for operating the webs, the operating means for each web including stationary posts and friction-rollers to insure against the webs slipping when in operation.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a perspective view of a calendar constructed in accordance with the invention.

Figure 2 is a rear elevational view of the device, the rear closure having been removed.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Figure 5 is a sectional view taken on line 5-5 of Figure 2.

Referring to the drawings in detail, the casing of the calendar is indicated generally by the reference character 5, the front wall thereof being formed with a cut-out portion 5 which is closed by a transparent wall, providing a sight opening.

Disposed within the casing and arranged at a point intermediate the ends thereof, is the powershaft 'c", on which shaft is secured the frictionroller 1, the roller 1 being of a length to extend over substantially one-half the lengths of the 2 power-shaft. A nut indicated at 8 is provided on the power-shaft and contacts the upper end of the friction-roller I, securing the frictionroller 1 to the shaft and at the same time providing a spacer for purposes to be hereinafter more fully described.

Cooperating with the friction-roller I is an idle friction-roller 9 which is mounted on the shaft lil disposed vertically of the housing, the friction-roller 9 contacting the web H which moves between the rollers I and 9 to feed the web through the casing. This web H is formed with vertical lines defining columns 12 in which indicia are provided indicating the days of the week. The endless web II also operates over the vertical stationary posts l3 which are disposed within the casing at the ends thereof, the friction-roller 9 contacting the web adjacent to one of the posts [3 to grip the web and cause the web to be fed through the casing without buckling.

Mounted on the power-shaft 6' and extending into the casing, is a tubular shaft [4 which is provided with an operating knob [5 whereby the shaft may be rotated from a point exteriorly of the casing. Secured to the inner end of the tubular shaft M is a friction-roller I6 which is disposed adjacent to the idle friction-roller H, the rollers l6 and I1 providing means to feed the endless web I8 through the casing so that the printed matter thereon will be displayed before the sight opening.

The web 18 also moves over the upper ends of the vertical posts l3 which act to prevent the Web over-running, durin the operation of the device to move the endless webs.

Pins [9 extend from the stationary posts l3 and provide stops adapted to contact with the upper edge of the web ll, while the lower edge of the web l8 contacts certain of the pins, holding the webs in their proper positions for alignment with the sight opening at the front of the casing.

A knob indicated at 2%] is provided On the upper end of the power shaft 6, so that the power shaft may be rotated independently of the tubular shaft.

Positioned within the sight opening is a partitioning member 2| which is formed with a cutout portion 22 providing an opening through which the printed matter on the web l8 may be viewed. This partitioning member also is provided with letters indicating the days of the week, so that when the endless web H is moved, certain dates of the month may be moved to align with certain letters indicating the days of the week.

From the foregoing it will be seen that due to construction shown and described I have provided a perpetual calendar which may be readily and conveniently operated to indicate the dates of the days of the week and month, the operating mechanism and the endless webs of the device being such that the endless-"webs will be held flat at all times and will not buckle to cause any unsightly appearance.

What is claimed is:

A calendar of the class described comprising casing having a display opening formed in the front wall thereof, vertical stationary posts having curved surfaces, mounted within the casing adjacent to the ends thereof, a vertical operating shaft disposed within the casing and being extended through the top of the casing, a friction-roller secured to the operating shaft and extending throughout substantially one-half of the length of the operating shaft, a frictionroller operating within the housing adjacent to the roller secured to the operating shaft, an endless web having indicia formed thereon operating over the posts and adapted to move between said friction-rollers, feeding the web before the display opening, a tubular shaft mounted for rotation on the operating shaft and having one end thereof extending through the top of the housin a friction-roller secured to the tubular shaft within the housing, an idle friction-roller contacting with the friction-roller mounted on the tubular shaft, an endless web carrying indicia operating over the posts and between the lastmentioned friction-rollers, whereby the latter web is moved before the display opening displaying indicia thereon.
